The iAd App Network will be discontinued as of June 30, 2016. Although we are no longer accepting new apps into the network, advertising campaigns may continue to run and you can still earn advertising revenue until June 30.
This also means that the iAd-supported free version of iTunes Radio will no longer be available.
Apple’s statement to BuzzFeed News, as reported by Brendan Klinkenberg:
We are making Beats 1 the premier free broadcast from Apple and phasing out the ad-supported stations at the end of January. Additionally, with an Apple Music membership, listeners can access dozens of radio stations curated by our team of music experts, covering a range of genres, commercial-free with unlimited skips. The free three-month trial of Apple Music includes radio.
I was pretty excited about iTunes Radio when it was first announced, but I can’t remember the last time I used the service.
